When 6.78 g of solid ammonium nitrate dissolves in 50.0 g of water at 18.9oC, the temperature of the solution drops to 4.0oC. What is q for the reaction?

Step 1

Given:

Specific heat of water = 4.18 J/g.^{ o}C

Mass of ring = 50 g

Mass of ammonium nitrate = 6.78 g.

Initial Temperature of water = 18.9 ^{o}C

Final temperature of water = 4.00 °C

Step 2

Heat loss or gain i...
